Europe's biggest mining project may be approaching the finish line after a dozen years of opposition and delays, and could enter its final stage late next year, a Rosia Montana Gold Corp executive told Reuters on Friday. Rosia Montana is majority-owned by Gabriel Resources which have spent more than $500 million under no fewer than seven different CEOs advancing the project since the Canadian firm first obtained the concession in 1999. It is believed the be one of the richest deposits in Europe with 314 tonnes of gold and 1,500 tonnes of silver and where mining activity dates back to the 1st Century.
